Just some ideas I had for fun rewards for next year, as well as a couple of housing improvements.
Better NPC capabilities in-home
Limiting the utility of the assistants you can summon makes sense, except when you're at home. Allow the banker full access to guild banks and stores, and give the vendor a repair option only when placed in a home. Give the fence normal vending values.
Wayshrines / Port Cost
Offer wayshrines of various flavors, which can be placed in the home to teleport out for free. If this is impossible because of the map system, at least make teleporting to your home not refresh the gold cost penalty as it currently does.
And for next year's festival...
Furnishing: Die Station
Looks just like the Dye Station but when used, knocks you back ten meters and instantly kills you. Jester's reward.
Assistant: Jester
House NPC that sells festival-specific flavor items, such as fireworks, for gold (also increase the collectible cap, already). This idea could apply to pretty much any holiday event with flavor items. Maybe it's a single vendor that changes appearance and personality for each season and only sells these items while it's in season.
